Hey,

like the title says, I completed the "Master Armorers" quest where I should collect all the stuff from the Skelligs Islands for Furges, but now I can't complete the quest since he wont talk to me. I can talk to the girl standing next to him (she sells me stuff) but not to him. I tried to meditate, tried it at different times of the day and I tried to save and reload the game but nothing helped.

Any ideas?

If saving and reloading didn't help then I suspect that either your installation is corrupt or a mod is interfering with proper functionality. Remove all mods and verify/repair your installation (assuming Galaxy).

Thanks for your answer. I didn't install any mods (didn't even know there are mods for this game, have to check them out!) and did the Verify / Repair thing in Gog Galaxy, which just ran through fine.

Did you save your game while you were standing next to Fergus? That is the proper way, so as to rule out any area transition glitches. Stand next to him, save the game, then immediately reload. This is actually a common problem -- interactive object glitches -- with a lot of games, not just The Witcher 3. The blacksmith in Kaer Trolde is notorious for this. It's actually a game engine issue.
